They kept calling and hanging up. I called them back once -- they hung up. They called again, early this morning and hung up. I blocked their number and assigned their name, 'D0uchebag'.
Keeps calling if i don't know the number i don't never answer it. If no message left i never call anyone back. I look at it as a debt collector really wants to talk they will leave a number. If not then they will not see any debt paid by me till they talk to me. Period. Too many phone scams out there to play games. No time for that drama [***] in my life.
